we went on boat when kids were 4 months and 2 years but we went to mainland. had a cabin and that was the best for us. was fine with kids. but because i was breastfeeding i couldn't take sea sick tablets and felt v sick and threw up too, that wasn't nice. where in tas are you planning on going ? .
theres so many places but your kids are still little so if you're wanting places you can go for them or for you but with them?
